CPIM - Certified in Planning and Inventory Management Detailed Scheduling Questions and Answers

Question 1

A work center's planned input is 100 standard hours, and the planned output is 100 standard hours.
Over the past week, the actual input was 90 hours, and the actual output was 80 hours.
What is the immediate conclusion a production planner should draw using input/output control?

Accepted Answer

A backlog of 10 standard hours has been created this week.

Answer

The work center is a bottleneck because its output is less than its input.

Answer

The work center's capacity should be permanently increased.

Answer

The work center performed with 80% efficiency.

Question 2

A manufacturing scheduler is using a finite loading approach. Which of the following is a key characteristic of this detailed scheduling technique?

Accepted Answer

It creates a realistic schedule by considering the actual capacity of resources.

Answer

Work is scheduled without regard to the capacity of work centers.

Answer

The schedule is created by backward scheduling from the order due date, assuming unlimited resources.

Answer

The primary goal is to identify and highlight resource overloads for manual adjustment.

Question 3

In a job shop environment with several orders competing for time on a single machine, which dispatching rule would prioritize the job that is most likely to be completed the soonest?

Accepted Answer

Shortest Processing Time (SPT)

Answer

Earliest Due Date (EDD)

Answer

First Come, First Served (FCFS)

Answer

Critical Ratio (CR)

Question 4

Which of the following detailed scheduling activities involves determining the specific order in which jobs will be run at a particular work center?

Accepted Answer

Operation Sequencing

Answer

Capacity Requirements Planning (CRP)

Answer

Material Requirements Planning (MRP)

Answer

Sales and Operations Planning (S&OP)

Question 5

A production planner is reviewing the output of their Capacity Requirements Planning (CRP) system. The report shows that a key work center is overloaded for the next two weeks. According to the principles of detailed scheduling, what is the MOST appropriate next step?

Accepted Answer

Use finite scheduling to create a realistic plan that respects capacity constraints.

Answer

Ignore the overload as it is likely a short-term issue.

Answer

Immediately authorize overtime and subcontracting.

Answer

Revise the Master Production Schedule (MPS) to reduce demand.

Question 6

Backward scheduling is a common technique used in detailed scheduling. What is the primary starting point for this method?

Accepted Answer

The order's required due date.

Answer

The availability of the bottleneck resource.

Answer

The earliest possible material availability date.

Answer

The start date of the first operation in the routing.
